are there more than 1 airport in Manila ? May I know any different in Manila Clark and Manila Aquio ? Which is more conventient ? Thanks for the help.

Clark Airport is not in Manila. It is on the borderline of a city called Angeles and another smaller area called Dau. Smaller airlines, discount airlines often use this (former U.S. Airforce) field. From there it takes around 2 to 4 hours to get to Manila, depending on traffic and type of transportation you get.

The other airport is the primary airport located in Manila, (MNL.) There is a second terminal used for domestic travel within P.I.

Depends on where you are coming from and the airline you choose as to which airport your flight lands at.
